Definition

- Glucocorticoid receptor agonist that mimic cortisol function by acting as agonists at the glucocorticoid receptor

- Inflammatory conditions

- Autoimmune diseases

- Replacement therapy for primary and secondary adrenal insufficiency

- Contraindicated in patients w/ systemic fungal infection

- tapered off slowly or can lead to acute adrenal insufficiency

- needs to be in active form if not in area that has 11β-HSDI (in liver)

- cleared from Kidney 11β-HSDII (kidney)

Term
Mifepristone (RU-486)
Definition

- Competitive antagonist of cortisol action at the glucocorticoid receptor (type 2)

- must monitor serum potassium level as well as BP

Term
Spironolactone + Eplerenone
Definition

- Mineralocorticoid receptor antagonist that are competitive antagonists of aldosterone action at the receptor
